Abstract

Çalışmanın amacı: Çalışmanın amacı Pterocarpus türlerinin yapraklarındaki tanen, flavonoid, saponinler, fenol, alkaloitler, terpenoidler ve anti-besin bileşikleri olan oksalat ve fitat açısından fitokimyasal içeriklerini belirlemektir.
Materyal ve yöntem: Analizler, P. osun, P. mildbraedii, P. soyauxii, P. erinaceus ve P. santaloides olmak üzere beş endemik Pterocarpus türünün toz halindeki metanol ekstraktları üzerinde standart prosedürler kullanılarak gerçekleştirildi.
Temel sonuçlar: Hem nitel hem de nicel analizler, yaprak örneklerinin ortalama konsantrasyon değerlerinde (mg/100g) değişiklik gösteren benzer fitokimyasal/ikincil metabolitler içerdiğini göstermektedir; tanenler (1.06-2.89 mg/100g); flavonoid (2.17-5.46 mg/100g); saponinler (2.78-9.38 mg/100g), fenol (1.13-2.56 mg/100g), alkaloidler (3.06-6.28 mg/100g), terpenoidler (1.32-2.46 mg/100g); oksalat (0.34-1.14 mg/100g) ve fitat (0.16-046 mg/100g). Elde edilen fotokimyasal değerler incelenen taksonlar arasında önemli ölçüde farklılık göstermiştir (p≥0.05).
Araştırma vurguları: Saponinler, fenol, tanen ve fitatın en yüksek konsantrasyonu P. mildbraedii yapraklarında bulunurken, P. erinaceus en yüksek flavonoid, alkaloid ve oksalat konsantrasyonunu içermiştir. Terpenoid oranı en yüksek olarak P. soyauxii yapraklarında bulundu. Genel olarak, incelenen Pterocarpus türleri düşük düzeyde anti-besin bileşiği içermiştir ve bu da onları tüketim için güvenli hale getirmektedir. Bu nedenle, çalışma bu cinsin yapraklarındaki zengin fitokimyasal içeriği ortaya koyarak, yapraklı bitkiler ve etnomedikal için etnobotanik kullanımlarını haklı çıkarmaktadır. Ayrıca, bulgular cins üyelerinin fitokimyalarına göre taksonomik yerleşimini ve sınıflandırılmasını destekleyen ek bilgiler sağlamaktadır.

Examining the Phytochemicals in Leaves of Pterocarpus Species in Nigeria

Abstract

Aim of study: The study carried out a phytochemical analysis for tannin, flavonoid, saponins, phenol, alkaloids, terpenoids and anti-nutrient compounds – Oxalate and phytate.
Materials and method: These were carried out on powdered leaf methanolic extract of five endemic Pterocarpus species viz; P. osun, P. mildbraedii, P. soyauxii, P. erinaceus and P. santaloides using standard procedure.
Main results: Both qualitative and quantitative analysis indicated that the leaves sample contained similar phytochemical/secondary metabolites with variation in mean concentration value (mg/100g); Tannins (1.06 - 2.89 mg/100g); flavonoid (2.17-5.46 mg/100g); saponins (2.78¬¬-9.38 mg/100g), phenol (1.13-2.56 mg/100g), Alkaloids (3.06-6.28 mg/100g), Terpenoids (1.32-2.46 mg/100g); Oxalate (0.34-1.14 mg/100g) and Phytate (0.16-0.46 mg/100g). These differed significantly (p≥0.05) amongst the examined taxa.
Research highlights: The highest concentration of saponins, phenol, tannin and phytate was found in leaves of P. mildbraedii while P. erinaceus contained the highest concentration of flavonoid, alkaloid and oxalate. However, terpenoid was found highest in leaves of P. soyauxii. Generally, the studied Pterocarpus species contained low level of anti-nutrient compound making them safe for consumption. Thus, the study revealed the rich phytochemical content in leaves of this genus to justify their ethnobotanical usage for leafy vegetable and ethnomedicine. Furthermore, findings provided additional information in support of the taxonomic placement and classification of members of the genus on the basis of their phytochemistry.
